Year Of No Light (often abbreviated as YONL) is a French post-metal band from Bordeaux formed in 2001. For their début album, Nord, YONL drew influence from several genres, including post-rock, sludge, somber psychedelics and depressive atmospheric shoegaze". The second album, Ausserwelt, was not released until 2010 after a significant line-up change in 2008 which established the band as an instrumental sextet, including two drummers and three guitarists. Ausserwelt saw the band's sound develop in the direction of black metal and doom metal while retaining a progressive, post rock feel.
